Human activities are reshaping all the TEarth’s systems so profoundly that a new geologic age, the Anthropocene, is upon us. The actions we take together right now are important for protecting the natural world we rely on today and for setting us on the path to a more hopeful, sustainable future. Many of the tremendous challenges facing society today—from resource scarcity to climate upheaval—can only be addressed by resetting and rebalancing how we interact with the natural world. Protecting, restoring, and managing natural systems to be more present at the Preserve and uses this framework to establish resilient to change, and thereby securing all the associated management recommendations for stewardship and program co-benefits that natural systems provide for people, will development across both longer (>5 years) and shorter (1-5 ensure more resilient human communities. Land protection years) time frames. The Nature Conservancy has been able has been a key strategy for The Nature Conservancy since to leverage an extensive amount of natural resource-based its beginning as a grassroots organization in 1951 and is even assessment and planning work that was conducted by the more important today. Globally, only 5% of the natural lands previous landowners and their consultants. However, there are at high risk of development are protected. Demands on land several near-term priority planning and assessment priorities and water continue to increase. Protected areas today must not at the Jack and Laura Dangermond Preserve, including the only provide protection for species and natural communities but development of a number of implementation plans—that will also adapt to change, serve as learning platforms for addressing be developed as resources become available—and will nest current and future conservation challenges, and help create under the Integrated Resources Management Plan and guide and engage the next generation of environmental leaders. on-the-ground management efforts. These include: • 5-year Grazing and Fire Management Plan In December 2017, The Nature Conservancy, through a gen- erous donation from Jack and Laura Dangermond, acquired • Natural Resources Monitoring Plan 24,460 acres of a former private ranch at Point Conception, • Road Management Plan California.

(AMEC) is pleased to provide the attached revised proposal to prepare an Environmental Impact Report (EIR) for the Carmel Canine Sports Center project. AMEC has assembled a strong team with directly relevant experience for this type of project. Highlights of our team’s capabilities and strengths include: . A Project Manager with substantial experience in environmental review and permitting of controversial projects in jurisdictions with high constituency involvement, including current management of a Project EIR in the Del Monte Forest Planning Area of Monterey County. A team with substantial experience preparing EIRs addressing controversial and complex development projects, including innovative approaches to water resource management, habitat and sensitive species compliance, and noise and traffic mitigation. A team with in-depth knowledge of federal, state, and local regulatory standards, processes, and requirements. AMEC’s team would conduct work from our Santa Barbara and San Francisco offices, while Central Coast Transportation Consulting, AMEC’s subconsultant for traffic analysis, would be based in Morro Bay.

  • Rare Plants of Santa Barbara County
    Rare Plants of Santa Barbara County Central Coast Center for Plant Conservation Santa Barbara Botanic Garden (SBBG) 1212 Mission Canyon Rd, Santa Barbara 93105 The purpose of this list is to bring attention to those vascular plant taxa with a limited distribution in Santa Barbara County, irrespective of their status, whether they are common elsewhere or whether they are considered imperiled, threatened, or endangered by resource management agencies. This list was prepared from records maintained as part of a specimen-based database at the Santa Barbara Botanic Garden. It includes plants from the mainland and four California Channel Islands (Santa Barbara, Santa Cruz, Santa Rosa, and San Miguel). Records were primarily acquired from verified herbarium specimens deposited at several herbaria, including the University of California at Berkeley (JEPS, UC), the California Academy of Sciences (CAS, DS), the University of California at Santa Barbara (UCSB), and the Santa Barbara Botanic Garden (SBBG). Additional records were acquired from peer-reviewed publications and professional reports that refer to specimens at other herbaria or verified observations (e.g., California Natural Diversity Database). Nomenclature follows The Jepson Manual (Baldwin et al., 2012), except for addenda published on the Jepson Herbarium Online Interchange (ucjeps.berkeley.edu/jepson_flora_project.html) and recent scientific publications (e.g., Flora of North America, 1999-2007, Oxford University Press). Additional information, including nomenclature and distributional records based on documented specimens, can be accessed on the Jepson Herbarium Online Interchange. Occurrences.
